JP 2002-255287 A

  In the ice storage type beverage cooling apparatus configured as described above, the beverage cooling pipe is supported by being lifted from the bottom surface of the cooling tank by the support member, so that the beverage in the beverage cooling pipe is the water in which the ice in the cooling tank is melted. Is not affected by. Although ice-melted water has a higher temperature than ice, freshly-melted water can sufficiently cool a beverage, which causes a problem of poor cooling efficiency of the ice-storage beverage cooling device. An object of the present invention is to provide an ice storage type beverage cooling apparatus that effectively utilizes water in which ice is melted in a cooling tank for cooling beverages.

  In order to solve the above-mentioned problems, the present invention includes a cooling tub that stores ice and a beverage cooling pipe that cools the beverage provided in the cooling tub, and the beverage that passes through the beverage cooling pipe is heated with ice and heat in the cooling tub. It is an ice storage type beverage cooling device that cools by replacing, and has a rising part that rises upward from the lower part of the cooling tank, and ice has melted in the cooling tank at a water level above the level of the height of the rising part It is an object of the present invention to provide an ice storage type beverage cooling device provided with a water level adjusting pipe for discharging water.

  In the ice storage type beverage cooling apparatus configured as described above, the water when the ice in the cooling tank melts is accumulated up to the height of the rising part of the water level adjustment pipe, and the beverage cooling pipe in the cooling tank has ice. Since it is also cooled by the water when it melts, the water in which the ice is melted can be effectively used for cooling the beverage in the cooling tank. In addition, the ice in the cooling tank is easier to float in the melted water because the specific gravity is lighter than that of the water, and the water in the cooling tank is lower in the upper part than the lower part in the range of the rising part due to the floating ice. ing. When the ice in the cooling tank melts, the water will be discharged from the lower part of the rising area, so the temperature of the melted ice in the cooling tank should be as low as possible. I was able to.

  In the ice storage type beverage cooling apparatus configured as described above, it is preferable that the water level adjusting pipe is provided with a descending portion that falls downward from the upper portion of the rising portion. When water in the cooling tank flows into the falling part without any gap beyond the rising part of the water level adjustment pipe, the water in the cooling tank is sucked up from the rising part by the principle of siphon, and falls and discharges the falling part. As a result, the water stored in the cooling tank can be automatically discharged, and the water in the cooling tank can always be kept cold.

  In the ice storage type beverage cooling apparatus configured as described above, it is preferable that the beverage cooling pipe raises the beverage introduced from the lower introduction portion and leads out from the upper lead-out portion. Beverages introduced from the introduction part at the lower part of the beverage cooling pipe are pre-cooled by the water in which the ice in the cooling tank has melted, and the beverages in the beverage cooling pipe pre-cooled by the melted water in the cooling tank to the upper outlet part Since it is further cooled by the ice in the cooling tank when it rises, the beverage passing through the beverage cooling pipe can be efficiently cooled. Also, since the beverage introduced into the lower part of the beverage cooling pipe is cooled in advance by the melted water at the lower part of the cooling tank, the ice that has been cooled in the lower part of the beverage cooling pipe rises in the ice in the cooling tank. However, the ice in the cooling bath can last longer.

It is the schematic of the ice storage type drink cooling device of this invention.

  Hereinafter, an embodiment of an ice storage type beverage cooling apparatus according to the present invention will be described with reference to the drawings. The ice storage type beverage cooling device (ice storage type beverage dispenser) 10 of the present invention can be installed even in a place without a power source, and cools beverages using block ice (cube ice), for example. As shown in FIG. 1, the ice storage type beverage cooling apparatus 10 of the present invention includes a cooling tank 12 that stores ice in a housing 11, and the cooling tank 12 is covered with a heat insulating material in the housing 11. A cover body 13 filled with a heat insulating material is provided at the upper surface opening of the cooling tank 12, and the cover body 13 covers the upper surface opening of the cooling tank 12 so as to be freely opened and closed. A pouring cock 14 is provided at the upper front of the housing 11, and a drain pan 15 is provided at the lower front of the housing 11. The dispensing cock 14 pours beverage from the nozzle 14b by tilting the lever 14a. The drain pan 15 is used for placing a container such as a glass for receiving a beverage poured out from the dispensing cock 14 below the dispensing cock 14 and for receiving a beverage overflowing from the container such as a glass. It is done. In addition, it is preferable that a drain pipe is connected to the drain pan 15 so that beverage or water received by the drain pan 15 is drained to a drainage place. A drain port 12a is formed on the bottom surface of the cooling tank 12, and a drain pipe 16 is connected to the drain port 12a. The distal end portion of the drain pipe 16 is led out below the drain pan 15 at the lower front portion of the housing 11, and the distal end portion of the drain pipe 16 is closed by a cap body 17 so as to be opened and closed.

  A beverage cooling pipe 20 for cooling the beverage is provided in the cooling tank 12, and the beverage cooling pipe 20 is erected in the cooling tank 12 while being wound in a coil shape. The lower portion of the beverage cooling pipe 20 is connected to the beverage barrel (beverage supply source) T via the beverage supply pipe 21, and the upper outlet portion of the beverage cooling pipe 20 is the dispensing cock 14 at the upper front of the housing 11. It is connected to the. The beverage barrel T is connected to a gas cylinder G filled with carbon dioxide gas, and the beverage in the beverage barrel T is sent out to the beverage cooling pipe 20 by the pressure of carbon dioxide gas fed from the gas cylinder G. The beverage fed from the beverage barrel T to the beverage cooling pipe 20 rises from the lower introduction part to the spiral of the beverage cooling pipe 20 and is guided to the dispensing cock 14 from the upper outlet part. The beverage passing through the beverage cooling pipe 20 is cooled by exchanging heat with ice in the cooling bath 12.

  A water level adjusting pipe 30 is provided below the cooling tank 12 to adjust the water generated when the ice stored in the cooling tank 12 melts to a predetermined level. The water level adjustment pipe 30 includes a rising portion 31 that rises upward from the lower portion of the cooling tank 12 in the heat insulating material in the housing 11, a falling portion 32 that descends from the upper portion of the rising portion 31, and a lower end of the falling portion 32. It has a lead-out portion 33 that extends forward and leads to a drain pan 15 at the lower front of the housing 11. The rising portion 31 adjusts the water generated when the ice melts in the cooling bath 12 so as not to exceed a predetermined water level that is the height of the rising portion 31. Water generated when the ice in the cooling bath 12 melts flows into the rising portion 31, and the water level in the cooling bath 12 becomes the same height as the water level of the rising portion 31. When the water in the cooling tank 12 tries to exceed the height of the rising part 31, the water in the cooling tank 12 is discharged from the rising part 31 through the falling part 32 and the outlet part 33, and the water level in the cooling tank 12. Is maintained so as not to exceed the height of the rising portion 31. The descending part 32 drains water exceeding the rising part 31 to the drain pan 15 together with the outlet part 33. Further, the water level adjusting pipe 30 is made of a pipe material that is thinner than the drain pipe 16, and the falling part 32 has a function of discharging the water in the cooling tank 12 together with the rising part 31 by the principle of siphon. Note that if the tube diameter of the descending portion 32 is made smaller than the tube diameter of the rising portion 31, the siphon phenomenon can be more easily caused.

  Next, cooling of the beverage by the ice storage type beverage cooling device 10 will be described. When the ice storage type beverage cooling apparatus 10 is used, the lid 13 of the cooling tank 12 is opened, and block ice is put into the cooling tank 12. In this state, when the lever 14a of the pouring cock 14 is tilted, the beverage in the beverage barrel T is introduced from the lower portion of the beverage cooling pipe 20 through the beverage supply pipe 21, and the coiled beverage cooling pipe 20 is moved. It rises and is led out to the pouring cock 14 from the upper lead-out part, and is poured into a container such as glass from the nozzle 14b of the pouring cock 14. The beverage passing through the beverage cooling pipe 20 is cooled by exchanging heat with block ice in the cooling bath 12.

  The block-shaped ice in the cooling tank 12 melts little by little under the influence of the beverage passing through the beverage cooling pipe 20 and outside air, and the water level due to the melted ice in the cooling tank 12 rises little by little. When the water level in the cooling tank 12 rises to the same height as the height of the rising part 31 of the water level adjusting pipe 30, the water in the cooling tank 12 flows from the upper part of the rising part 31 to the falling part 32, and the falling part 32 and the outlet part 33 and discharged to the drain pan 15. At this time, when the water in the cooling tank 12 flows from the rising part 31 into the falling part 32 without a gap, the water in the cooling tank 12 is sucked up from the rising part 31 and falls down the falling part 32 according to the principle of siphon. Then, it is discharged to the drain pan 15. Since the water dissolved in the cooling tank 12 is discharged according to the principle of siphon, the water dissolved in the cooling tank 12 is automatically discharged, and the cold state can always be maintained. Further, when the amount of ice in the cooling tank 12 decreases, the ice in the cooling tank 12 floats because the specific gravity is lighter than the melted water, and the water stored in the lower part of the cooling tank 12 rises. In the range, the upper part is lower in temperature than the lower part.

  In the ice storage type beverage cooling apparatus 10 configured as described above, the block type ice in the cooling tank 12 melts little by little due to the influence of the beverage passing through the beverage cooling pipe 20 and the outside air, and the water level in the cooling tank 12 The melted water accumulates at the height of the rising portion 31 of the adjustment pipe 30. The water in which the ice has just melted in the cooling bath 12 is cold and can be used for cooling the beverage, and the beverage passing through the beverage cooling pipe 20 is cooled by the melted water stored in the lower portion of the cooling bath 12. The cooling efficiency of the beverage passing through the beverage cooling pipe 20 in the tank 12 could be increased. Further, when the water melted in the cooling tank 12 exceeds the height of the rising part 31 of the water level adjusting pipe 30, it is discharged to the drain pan 15 through the falling part 32 and the outlet part 33. The water stored in 12 can be suppressed to the extent that the ice on the top is not melted, and it is no longer necessary to discharge the water when additional ice is added into the cooling bath 12. Furthermore, since the water when the ice in the cooling bath 12 melts is discharged from the lower part of the rising portion 31 with a high temperature, the temperature of the melted ice in the cooling bath 12 is as low as possible. The beverage passing through the lower portion of the beverage cooling pipe 20 can be cooled with water having a temperature as low as possible.

  Further, the water level adjusting pipe 30 has a descending part 32 that descends from the upper part of the rising part 31, and a thin pipe material is used so as to easily cause a siphon phenomenon. When the water in which the ice in the cooling bath 12 has melted flows into the falling portion 32 beyond the rising portion 31 of the water level adjusting pipe 30 without a gap, the water in the cooling bath 12 flows from the rising portion 31 according to the siphon principle. The water that has been sucked up and falls down and is discharged, the water stored in the cooling tub 12 can be automatically discharged, and the water in the cooling tub 12 can be always kept cold. . In this embodiment, the water level adjusting pipe 30 is configured to cause a siphon phenomenon by the rising portion 31 and the falling portion 32. The present invention is not limited to this, and water in the cooling tank 12 cannot be automatically discharged due to the siphon phenomenon. However, the water level adjusting pipe 30 is provided with only the rising portion 31 so that the inside of the cooling tank 12 is provided. The water in which the ice has melted may be discharged at a height exceeding the rising portion 31.

  In the ice storage type beverage cooling apparatus 10, the beverage introduced from the lower introduction portion of the beverage cooling pipe 20 is raised and led out from the upper outlet portion. Specifically, the beverage cooling pipe 20 is erected in the cooling tank 12 in a state of being wound in a coil shape with the upper and lower sides being the axis direction of the winding, and the beverage cooling pipe 20 wound in the coil shape The beverage introduced from the lower introduction part is raised and led out from the upper lead-out part. The beverage introduced into the introduction part at the lower part of the beverage cooling pipe 20 is first cooled in advance by water when the ice melts in the cooling tank 12, and is then cooled to the outlet part at the upper part of the beverage cooling pipe 20. The ice in 12 further cooled, and the beverage passing through the beverage cooling pipe 20 can be efficiently cooled. Furthermore, since the beverage introduced into the beverage cooling pipe 20 is cooled in advance by the melted water at the lower part of the cooling tank 12, the beverage that has been cooled in the lower part of the beverage cooling pipe 20 rises in the ice in the cooling tank 12. However, it has not melted much, and the ice in the cooling bath 12 can be made to last for a long time. In addition, although the drink cooling pipe 20 is wound in the shape of a coil, what raises the drink introduced from the lower introducing | transducing part and derives | leads out from an upper derivation | leading-out part is the most preferable thing for obtaining said effect. The present invention is not limited to this, and may have a meandering shape in which the beverage cooling pipe is meandered from one to the other, for example.
